re: The biggest problem in schools that no one is talking about

Question 1 What is the root cause (s) of your staff"s inability to write effectively?
a) they were taught by people who didn't know how to write themselves
b) they were taught by people too lazy to properly grade written homework and test assignments
c) all of the above

Students cannot write because most assignments and tests require very little actual writing and composition. It's very time consuming to grade papers and tests where students write sentences and paragraphs. Multiple choice and other objective type tests are easier to grade and that's what most teachers assign. Not writing out answers to questions on a regular basis negatively impacts a student's ability to reason and reach conclusions. So not only can they not write, they can't think. It's a shame really.
PS I make this criticism as a former high school teacher and junior college math professor. Oh and don't get me started on online assignments and testing
